Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed July 18, 1905. Serial No. 270,245.

To all whom, it may concern:

Be it known that I, WILLIAM MOUNTAIN, a citizen of the United States,residing at Alexandria, in the county of Madison and State of Indiana,have invented new and useful Improvements in Rolls, of which thefollowing is a specification.

The invention relates to an improvement in rolling mills of the typedesigned for breaking down steel or iron piles for the production ofmerchantable bars.

The main object of the present invention is the production of a mill ofthe type described in which the pile is subjected to the action of aseries of sets of alternately horizontally and vertical rolls mounted ina common line of feed and continuously driven from a single shaft.

The preferred embodiment of the details of structure of my inventionwill be described in the following specification, reference being had tothe accompanying drawings, in which Figure 1 is a view in side elevationof a mill constructed in accordance with my invention. Fig. 2 is a planof the same. Fig. 3 is a rear end view of the same. Fig. 4 is anelevation of the finishing-mill. Fig. 5 is an end view of the same.

Referring to the drawings, it will be noted that I have illustrated buttwo sets each of the vertical and horizontal rolls, though it is to beunderstood that I contemplate the use of as many sets as may be founddesirable.

In the drawings, 1 represents a suitable bed-plate on which aresupported housings 2 andv 3, the former supporting thehorizontally-arranged rolls and the latter the vertically-arrangedrolls, one of the housings 2 being secured to the forward end of thebedplate and the remaining housings alternating therewith to provide apair of verticallyarranged rolls intermediate and beyond thehorizontally-arranged rolls, as clearly shown in Fig. 1.

The housings 2 are formed on the adjacent facings of their vertical barswith guide-webs 4, extending vertically of the housings, and receivingand guiding blocks 5, in which blocks is revolubly mounted the upperhorizontal roll 6.

7 represents the housing-cover, preferably of skeleton form and securedto the housing proper through the medium of screws 8.

Adjusting-screws 9 extend vertically through the transverse end bars ofthe cover,

being terminally secured to the journalblocks 5, the screws 9 havingthreaded engagement with said transverse bars to permit the verticaladjustment of the upper horizontal roll, as will be evident.

The lower horizontal roll is mounted in blocks 10, slidably engaging thevertical bars of the housing, the shaft 11 of this roll 12 beingprovided beyond the housing with a beveled gear 13.

The above description is equally applicable to both sets ofhorizontally-arranged rolls, it being understood that they are induplicate throughout the mill.

The vertically-arranged rolls 14 and 15 are mounted in a housing 3, theshafts16 and 17 of said rolls, respectively, being mounted in journal-blocks 18 and 19, grooved at 20 to receive webs 21, projectingfrom horizontal rails of the housing, whereby said rolls are adjustable.Screws 20 and 21, terminally connected to the blocks 18 and 19,respectively, have threaded bearings in the end bars of the housing,whereby said blocks 18 and 19, and thereby the verticallyarranged rolls,may be adjusted to accommodate themselves to the size of the pile. Thelower ends of the shafts 16 and 17 are provided with beveled gears 22and 23, respectively, removably secured on said shafts through themedium of collars 24, as is usual.

25 represents the main shaft of the mill, being supported in suitablebearings in the bed-plate and directly underlying the first or forwardpair of vertically-arranged rolls. Immediately beneath said rolls thisshaft is provided with two reversely-arranged beveled gears 26 keyed forlongitudinal movement upon the shaft 25 and arranged so that they engagethe beveled gears 22 and 23 respectively, of the vertically-arrangedrolls. In the transverse adjustment of the rolls to increase thedistance between them the gears 26 are spaced apart upon the shaft 25 toinsure the operative meshing with the gears 22 and 23, a spacing-collaror other device being employed to maintain the gears 26 spaced to thedesired extent.

It is to be understood that the second pair of vertically-arranged rollsare also provided with a shaft 27 therebelow, having keyed pinionssimilar in construction and operation to thepinions 26 on shaft 25.

The shafts 25 and 27 are each provided at one end with a beveled pinion28, arranged in longitudinal alinement and driven from a lower ends withbeveled pinions 34, arranged to intermesh on opposite sides of its axiswith the beveled pinion 31 on the shaft 35. The upper or remote end ofeach of the shafts 32 is provided with a beveled 'pinion 35, keyed uponthe shaft and held in adjusted position with relation to the shaft byany suitable means. The pinions 35 arearranged to intermesh with thepinions 13 on the lower roll of the horizontally-arran ed sets, wherebysaid rolls are driven from t e main shaft.

36 represents a feeding-scoop to receive a' pile of welding hot iron orsteel and direct the same to the first pair of horizontally-arrangedrolls.

Figs. 4 and 5 represent the finishing-mill, which is designed to receivethe material from the mill previously described. The finishing-millcomprises a base 36, from which rise standards 37, supporting the shafts38 on the finishing-rolls 39. The shafts of these rolls are preferablymounted in bearing-blocks which are secured against independent movementunder normal condition by set-screws 40, passing through thehousing-standards, though it is to be understood that set-screws 40 maybe adjusted when desired to permit a yielding movement of the rolls toaccommodate thicker piles.

Intermediate the respective pairs of hori 'zontally and verticallyarranged rolls are Shafts 32 are supported by bear mounted guide-rollers41, revolubly supported in uprights 43, whereby to guide and to supportthe iron piles in transit from one set of rollers to the next.

The operation of my improyed mill is fully apparent from the abovedescription taken in connection with the drawings.

vI-Iaving thus fully described the invention, what I claim as new is 1.A rolling-mill comprising a bed, three housings mounted thereon, a pairof rollers j ournaled in each housing, the rollers of the intermediatehousing being arranged at right anglesto the'remaining pairs of rollers,a driveshaft arranged beneath and adapted to coop erate with theintermediate pair of rollers, and drive-shafts connected with thefirst-mentioned drive-shaft and geared to operate one roller of each ofthe remaining pairs of rollers.

2. A rolling-mill comprising a bed, independent housings mountedthereon, a pair of rollers j ournaled in each housing, the rollers ofone pair being horizontally arranged and the rollers of the adjacentpair being vertically arranged, the shafts of the vertically-arrangedrollers projecting below the housings and provided with beveled gears, adriveshaft beneath one pair of vertically-arranged rollers, beveledgears on said shaft to engage the gears on the roller-shafts, meansconnecting said drive-shaft with the horizontally-arranged rollers, anauxiliary shaft beneath the remaining pairs of vertically-arrangedrollers, gears on said auxiliary shaft to engage the beveled gears onthe roller-shafts, and a connection betweenthe power-shaft and saidauxiliary shaft.

In testimony whereof I affix my signature in presence of two witnesses.
